Penile epithelioid sarcoma and the case for a histopathological diagnosis in Peyronie's disease

Abstract

Many of the previously reported cases included signs and symptoms of urethral narrowing or compression, causing lower urinary tract symptoms. In addition, the penile nodule size was reported to progressively enlarge over time. Because of the high prevalence of Peyronie's disease and low prevalence of ES, biopsy of every penile nodule is not judicious. However, signs and symptoms of urethral obstruction, and a progressively growing and persistently painful nodule should suggest a possible malignancy and warrant biopsy.
